The 2006–07 campaign remains his greatest domestic success to this day, and his last season with Stuttgart as in December 2006 he did not accept the club's offer to extend his contract.

[17] He made his Bundesliga debut for Hoffenheim on 31 January 2009 in their 2–0 win at home to Energie Cottbus, being substituted in the 60th minute due to an injury.

After Hildebrand left Sporting, he was on trial with Manchester City on their pre-season tour of USA before the 2011–12 season,[20] but they did not take up the option to sign him.

[21] Hildebrand signed onto Schalke 04 in the middle of the 2011–12 Bundesliga campaign after starting keeper Ralf Fährmann was injured.

[22] On 25 September 2014 Hildebrand signed for Eintracht Frankfurt in the wake of a major injury to their first-choice keeper Kevin Trapp.

[27] After Kahn's retirement from international football in 2006, Hildebrand stepped up to become Germany's number two and was Jens Lehmann's natural replacement during the Euro 2008 qualification.

[28] Somewhat surprisingly, Joachim Löw dropped Hildebrand from the final squad for the tournament and picked Robert Enke and René Adler ahead of him.

Although Löw stated that Hildebrand was an important player and may return to the set-up in near future,[29] he never appeared for Germany since his omission from their squad for Euro 2008.
